MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent N 0. 448,713, dated March24, 1891.

Application filed July 14, 1890.

To all whom it may concern.-

Be it known that we, RICHARD LONGDEN HATTERSLEY and JAMES HILL, subjectsof the Queen of Great Britain, residing at Keighley, in the county ofYork, England, have invented an Improvement in Mechanical Movements, ofwhich the following description, together with the accompanyingdrawings, is a specification.

This invention has for its object the formation and disposition of twoseries of levers and their respective shafts and connectingrods for thepurpose of effecting, when put into operation, by series of hooked jacksmounted upon one of these series of levers being made or allowed toengage with reciprocating draw and push bars, the movements of a thirdseries of levers in a positive manner, as also the looking or rigidlyholding of this said third series of levers at each extremity of theirmovements, so that any force acting through this third series of leverswhen they are at the said extremities of their movements is withstood byseveral stationary shafts, upon which said several series of levers aremounted. The particular uses for which these devices are fitted are theoperating of the heddles or the shuttle-boxes of looms for weaving, andthe usual and wellknown connecting parts are employed for connectingthese said mechanisms to those of said looms.

The object of our invention is attained by the mechanism illustrated inthe accompanying drawings in which- Figure 1 is an elevation of theparts shown as mounted upon a board or panel A instead of upon theordinary frame work, which would have interfered with the clearness ofthe View. Those parts of the mechanism which in an ordinary way wouldextend across from the frame-work on one side of the machine to that 011theother are here shown in section. Fig. 2 is a top view of parts shownby Fig. 1; and Fig. 3 is a similar view to Fig. 1, but shows therelative positions of the several parts when moved soas to bring thethird series of levers a to the other extremitiy of their movement thanthat shown by Fig. 1. y

In all the drawings, in order to simplify the serial No. 858,613. (Nomodel.)

view, only one lever, together with its several parts, out of each ofthe three series of levers is shown, as from this it will readily beseen how the remaining parts of each series are to be arranged.

Similarletters refer to similar parts throughout the several views.

The lever (it represents the series of levers herein referred to as thethird series, and is shown as being mounted upon its shaft b by spanningthe same, so that when its retainingrod 0 is removed it may be readilydetached at the time it is forming one of the series without in any waydisturbing or displacing any other in the same series. The levers d ande representthe two other series of levers,

the same being mounted upon the shafts f and g, respectively, andcoupled together and to the lover a by the rods h and k. The hooked jackZ is coupled to or made to lay hold of the pin an, attached to the rodh, and is made to extend horizontally tobe in proximity with the drawand push bars at and n, to or from which they are made to lay hold or tobe clear of by means of the peg-lags or pattern-surface 0 on thepattern-cylinder 19, operating same in the well-known manner through thelever r. The draw and push bars n and n are reciprocated by the rodstand 25', (shown in broken lines, Figs. 1 and 3,) being coupled therebyto the oscillatory lever to, which receives its oscillatory motionthrough the rod 4) from any suitable motor, such as a crank attached toor formed on a rotary shaft driven by any prime motor.

Now, when the rod h has been moved by the jack Z into the position shownby Fig. 1 said rod It will have moved the lever d into the positi onforthe center of its pin 62' and that of the pin 71/ on said rod h to bein line with the I center of the shaft f, in which position the lever 6and the rod 70, as also consequently the lever a, (the position of whichis now at the extremity of its onward 'movement,) will be locked orrigidly held by reason of these several centers being in line with eachother, while when the rod h has been moved into the position shown byFig. 3 the lever e and the rod is will have been thereby moved into theposition for the center of the pin is on the rod is and that of the pina on the lever a to he in line with the center of the shaft g, in jackZ, the bars n and n, the rods 25 and If, to which position said lover a(which has now and the lever u,in eombination,all these sevreached theother outward extremity of its eral parts being mounted, constructed,and movement) will be locked or rigidly held arranged tooperatesubstantiallyas specified.
